Sonoglass® is a fiberglass based, spray applied acoustical treatment designed to provide superior acoustical values with a finished appearance. Sonoglass® will adhere to almost any surface configuration. This makes it ideal for applications to curved and irregular shaped ceilings such as those found in churches, gymnasiums and theaters. With only a thin application of Sonoglass®, noise reverberation times can be greatly reduced, improving audibility and comfort at a reasonable cost

Improved Noise Reduction Properties
With only a thin application of Sonoglass, noise reverberation time can be greatly reduced, improving audibility and comfort at a reasonable cost.
Sonoglass is a fiberglass based, spray applied acoustical treatment designed to provide superior acoustical values with a more finished appearance than our standard Monoglass Spray-On insulation.
Sonoglass will adhere to almost any surface configuration. This makes it ideal for applications to curved and irregular shaped ceilings such as those found in churches, gymnasiums and theaters.
